| Abstract: | Immunological methods for the detection of basic fibroblast growth (FGF) are described. Polyclonal antibodies directed against synthetic peptides representing amino-, internal, and carboxy-terminal regions of basic FGF, were raised in rabbits. Five techniques, enzyme-linked immunosorbent assay, immunoblot, electrophoretic transfer (Western) blot, immunoprecipitation and radioimmunoassay, were used to detect basic FGF. These techniques were used to demonstrate that a human hepatoma cell line synthesizes a growth factor structurally related to brain and pituitary basic FGF. |
